Multilayer PCB yog dab tsi thiab nws qhov zoo?
May 17, 2022
Printed circuit boards yog tam sim no qhov chaw tseem ceeb tshaj plaws hauv electronics. PCBs siv yav dhau los tau yooj yim heev thiab raug txwv rau ib txheej. Niaj hnub no PCBs yog complex thiab hu ua multi-layer PCBs. Cov uas muaj kev ua haujlwm tsawg yog ib txheej txheej, thaum cov uas muaj ntau yam kev ua haujlwm yog tsim los ntawm ntau txheej. Cov PCB ilv yog siv rau cov motherboards thiab lwm yam. Multilayer PCBs yog tam sim no cov khoom tseem ceeb ntawm complex electronic circuits.

Multilayer PCB yog dab tsi?
Multilayer PCB tuaj yeem txhais tau tias yog PCB ua nrog 2 lossis ntau dua cov txheej txheem ntawm cov ntawv ci. Conductive foils zoo li muaj ntau txheej txheej ntawm lub rooj tsav xwm ntau yam. Cov txheej txheej sib txawv yog laminated ua ke thiab tom qab ntawd sib koom ua ke, tab sis thermally tiv thaiv nrog ib txheej insulating ntawm cov khaubncaws sab nraud povtseg. Muab cov khaubncaws sab nraud povtseg nyob rau hauv ib txoj kev uas ob sab ntawm PCB nyob rau saum npoo. Vias yog lub hauv paus ntawm kev sib txuas hluav taws xob ntawm cov txheej txheem sib txawv ntawm ntau lub PCB. Vim muaj kev nthuav dav ntawm kev lag luam hluav taws xob, muaj kev nkag siab ntawm kev xav tau ntawm 4- txheej PCBs thiab siab dua. Cov teeb meem nrog PCBs xws li suab nrov, crosstalk, thiab stray capacitance kuj tau hais txog lub sijhawm, thiab PCBs tsis muaj tag nrho cov teeb meem niaj hnub no. Qhov zoo tshaj plaws yog tias PCBs tam sim no muaj cov qauv tsim sib txawv thiab txoj hauv kev zoo tshaj plaws uas ua rau lawv txaus nyiam hauv cov khoom siv hluav taws xob.
Qhov zoo ntawm 4- txheej thiab siab dua PCBs
Cov hauv qab no yog cov txiaj ntsig tseem ceeb ntawm multilayer PCBs.
Qhov me me: Qhov me me ua rau cov PCBs no tseem ceeb heev vim tias qhov loj ntawm cov thev naus laus zis tau me dua thiab me dua nrog cov khoom siv hluav taws xob thiab hluav taws xob. Cov txheej txheem tsim ntawm PCBs muab me me rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob xws li khoos phis tawj, smartphones, ntsiav tshuaj, wearables thiab laptops, thiab lwm yam.
Raws li tau hais los saum no, 4- txheej PCBs thiab siab dua yog qhov me me, yog li cov PCBs no zoo rau cov khoom siv niaj hnub no.
Zoo: Ib qho tseem ceeb ntawm PCB hom no yog nws qhov zoo, raws li kev npaj yog nyob rau hauv nws cov creation. Cov txiaj ntsig ntawm cov ntawv luam tawm Circuit Board no zoo heev thiab tsis muaj teeb meem thoob plaws hauv lawv lub neej.
Durability: Txheej PCBs yog qhov ruaj khov vim tias tsis yog lawv tuaj yeem tiv taus qhov hnyav hnyav, tab sis lawv kuj tuaj yeem tiv taus qhov kub thiab txias. Muaj ib txwm rwb thaiv tsev ntawm cov txheej txheem sib txawv hauv cov PCBs no los muab kev tiv thaiv los ntawm kev puas tsuaj.
Flexible Designs: Cov PCBs tam sim no kuj muaj nyob rau hauv cov qauv siv tau yooj yim, tab sis tag nrho cov multilayer PCBs tsis hloov tau. Ib qho yooj yim 4- txheej PCB lossis siab dua tuaj yeem muaj txiaj ntsig zoo yog tias yuav tsum tau khoov me ntsis. Txawm li cas los xij, tag nrho cov PCBs no tsis hloov pauv.
Lub Hwj Chim: cov feem ntawm cov pcbs no yog qhov siab ntom thiab muaj cov txheej txheem sib txawv uas ua rau ib-txheej pcb. Cov cheeb tsam uas nyob ib sab no ua rau cov laug cam txuas ntxiv, thiab cov khoom siv hluav taws xob ntawm cov PCBs tso cai rau lawv muaj zog dua.
